Move over, Tina Fey: Julianne Moore is Sarah Palin in HBO film

Sarah Palin impersonators have some new competition -- Julianne Moore. So pack your moose-hunting bags, Tina Fey.

HBO has released the teaser trailer for "Game Change," a film starring Moore as the polarizing former Alaska governor when she debuted on the GOP ticket in 2008. It chronicles the campaign from the moment she stepped out as GOP nominee John McCain's pick for vice president leading up to their ultimate defeat in the presidential election. Watch the trailer below.

Moore, who recently starred in "Crazy Stupid Love," is the newest addition to the ranks of Palin impersonators, joining the likes of comedian Kathy Griffin and "30 Rock" writer Fey, who uncannily parodied the "Sarah Palin's Alaska" star on "Saturday Night Live" soon after she was announced as McCain's running mate. Maybe Moore's stints alongside Fey on "30 Rock" helped her hone that spot-on impression?

The Jay Roach-directed film based on John Heilemann and Mark Halperin's bestselling book also stars Ed Harris as McCain and Woody Harrelson as campaign strategist Steven Schmidt. Emmy-winning "Recount" writer Danny Strong wrote the script.

See Moore in her pump-wearing, camera-winking, "you betcha" phenomenon this March.
